TRANSOM-LIFTER.

Specification of Letters Patent.

Patented July 1, 1913.

Application filed December 28, 1908. Serial No. 469,609.

To (6 whom it may concern Be it known that I, WVILLIAM F. ORoUnKn, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Transom-Lifters, of which the following is a full, clear, concise, and exact description.

My invention relates to a transom lifter, and its object is to provide an improved, simple and readily operated device by which a transom or other adjustable window sash may be adjusted and rigidly held in position.

The preferred embodiment of my inven- 'tion consists of a traveling rod-clamp slidably adjustable on a rod which is adapted to be secured in fixed position upon one side of the frame in which the sash is adjustably supported, the brace for holding the sash in its adjusted position being secured to and movable with said clamp, and the movement of said clamp being controlled by a lift rod connected to the rod clamp.

The scope of my invention is set forth in the appended claim, it being understood, however, that my invention in its broader aspects does not consist in any particular form of traveling locking device or support therefor except as specified in the claim, or any particular connection between the looking device and its operating rod. Moreover, the invention is not confined to use in connection with any particular type of adjustable sash, but may readily be modified to make it applicable to the several wellknown types in common use.

I have shown the preferred embodiment of my invention in the accompanying drawings, in which- Figure 1 is a front elevation of my invention as applied to a hinged transom; and Fig. 2 is a side elevation thereof.

Similar reference characters designate parts wherever shown.

Fixed upon one side of the transom frame 1 in which the swinging transom 2 is mounted is a support 3, for a traveling sash-locking device l. Said support and locking device are shown as consisting of a vertically disposed rod 3 on which a well known type of rod-clamp 4 is longitudinally adjustable.

The sash locking device 4 consists of a housing or frame 5, open at the top and having its side walls connected by a middle arch (3. livoted at their ends in the bottom of the housing 5 are two clamping lovers 7, 8, provided with alined openings to receive the rod 3 upon which the rodclan1p is adapted to travel. The lovers 7, 8, are normally pressed apart by an interposed coiled spring 9, and thus normally engage with the rod 3 to lock the rod-clamp in engagement with its supporting rod. Referring to the drawings, it will be noted that the lever 7 looks the rod-clan'ip against downward movement, and the lever 8 likewise looks it against upward movement.

The brace 10 is connected in any suitable way with the adjustable sash. In the draw ings the lower end of the brace is shown as connected by a swivel joint 11 with an angular bracket 12 affixed to the transom. The other end,of the brace 10 is secured to the rod-clamp 4 To provide for the swinging adjustment of the transom the brace 10 has its upper end pivoted at 13 to the housing 5 of the rod-clamp.

Any suitable means for adjusting the rodclamp up or down upon the rod 3 may be used. That which I preferably employ is a lift rod 141:, the lower end of which is accessible to the operator and the upper end of which passes through alined holes in the outer ends of the lovers 7, 8. Means are provided, such as flanges 15 upon the outer sides of said lovers, to secure the end of said rod to said lovers in such manner that said rod may be employed to operate one of said levers independently of the other. For example, by pulling downward upon the lift rod 14: the lever 7 is moved against the arch 6, in which position the rodclamp is locked only by the lower lever S, which latter lever, as before stated, locks the clamp only against upward movement. By continued pull, therefore, upon the rod 14, the clamp-rod l is caused to slide downward upon the rod 3 to adjust, the transom sash to any desired open position, as indicated in dotted lines in Fig. 2. In a similar manner, by pushing upon the rod 14,-the lever S is released and the rod-clamp is caused to slide upward to close the transom.

It will be observed that to open or close the transom, it is necessary only to pull or push, respectively, upon the rod 14. The

transom may thus be easily and readily adjusted, the use of one hand only being required to operate the transom lifter.

The combination with a fixed rod, of a r0d-clamp adjustably mounted thereon, said rod-clamp being provided with a pair of pivoted clamping levers each having two holes in its free end in alinement with the corresponding holes in the other lever, said fixed rod extending through one pair of said alined holes, and a spring interposed between said levers to normally press the same apart into locking engagement with said fixed rod, alift rod having one end;

extending loosely through said other pair of alined holes in said clamping levers, said lift rod being provided with flanges upon the outer sides of said levers-for securing said lift rod to said levers, and means for voperat-ively connecting said rod-clamp to an adjustable sash.

In witness whereof, I hereunto subscribe my name this twenty-fourth day of Decemher, A. 1)., 1908.
